1. FC - FC fiber optic patch cords: FC (Ferrule Connector）optical fiber Connector is usually round metal sleeve, fastening screw type, this paper is mainly used in the distribution frame. The earliest, FC type connector, adopt the butt end of ceramic pin is plane contact way. Such connector has simple structure, convenient operation, easy, but the dust sensitive optical fiber end face, and prone to Fresnel reflex, is difficult to improve properties return loss. Later, for this type of connector is improved, the butt end of spherical pin, threaded connector generally are round, and external structure has not changed, the insertion loss and return loss performance has improved significantly.

2. ST - ST fiber optic patch cords: ST (straight trip) also circular optical fiber connector, pin and adopted by the coupling sleeve structure has the same size and FC, the pin end of different is that it is used more PC type, type or APC grinding way; And fastening way as the turnbuckle. This kind of connector is suitable for various optical fiber network, easy to operate, and has a good interchange ability.

3. LC - LC fiber optic patch cords, LC type optical fiber connectors compression in the entire network panel, wall panel and the space distribution box, make it occupies the space of half of the traditional ST and SC connectors. At present, in a single-mode SFF (small size), LC type of connector has occupied the dominant position, actual application in the field of multimode is also growing rapidly.

4. Adopted by the SC fiber optic connector shell shows square, pin type and the structure of the coupling sleeve size and FC are exactly the same, the end of the pin is used more PC type, type or APC grinding way; Fastening way is to use plug pin bolt type, do not need to rotate. Figure 5 for a both ends for SC connector SC - SC fiber optic patch cords.

Product Highlights:

Using extra high precision ceramic ferrule with small concentricity error and core diameter, better insertion loss and return loss can be achieved for optimized transmission performance.

All fiber surface parameters such as the apex offset, fiber height and radius of curvature comply to IEC standard.

Besides attenuation and back reflection testing, cords are also checked by interferometer for fiber surface parameters, including radius of curvature, apex offset and fiber heights for different FC, ST, SC, LC and MU connector types.

Simplex, duplex and fan-outs can be offered.

Different jackets such as PVC and LSZH grade available for selection.

Low insertion loss and high return loss, with excellent interchangeability and repeatability.

Durablity, damp-proofing, resistant to coupling stress, high pull tension and adaptation to different harsh environment such as dampness, extreme temperature, impact and vibration in accordance to ANSI/TIA and ISO/IEC standard.

Environmentally stable, meeting Telcordia requirement
